What is professional liability insurance?

Professional liability insurance, also called errors and omissions (E&O) insurance, pays when a client claims that your advice, design or service cost them money. It responds to claims about the quality of your work, not to injury or damage to property.

Even a claim without merit costs money to defend. That is what this coverage is built for, and it is why consultants, freelancers and licensed professionals are often asked to carry it before a client signs a contract.

Negligence and errors
A mistake, oversight or missed deadline in the work you delivered that led to a client’s financial loss.
Defence costs
Legal fees to defend a claim, even one without merit, from the first letter through to resolution.
Settlements and judgments
The cost of a settlement or a court-awarded judgment, up to your policy limit.
Lost documents or data
Claims arising from client documents or data lost, damaged or improperly disclosed while in your care.

Who needs professional liability insurance?

Anyone who gives advice, designs something or delivers a service where a mistake could cost a client money. A good test: if a client could argue that your work, not just your product, caused them a loss, this coverage is relevant to you.

Consultants
Business, management and specialist consultants whose advice clients act on.
IT and software
Contractors and developers whose work keeps a client’s systems running.
Accountants and bookkeepers
Anyone handling a client’s numbers, filings or deadlines.
Designers and creatives
Designers, writers and studios delivering work to a client’s brief.
Engineers and architects
Licensed professionals whose designs and sign-offs others rely on.
Marketing and media
Agencies and freelancers promising results from campaigns and content.

What does a real claim look like?

These examples are illustrative, not real cases. In each one, the cost of defending the claim is what the policy is built to pay for, whether or not the claim succeeds.

A marketing consultant
The consultant recommends an advertising strategy that underperforms. The client says the plan was negligent and sues to recover what they spent. The policy pays for the legal defence, and for a settlement if one is agreed, up to the limit.
An IT contractor
A configuration error takes a client’s system offline for a day, and the client claims lost sales. The policy responds to the claim about the work. A data breach would be a different matter, and usually needs a separate cyber policy.
A bookkeeper
A missed filing deadline leads to penalties that the client says were the bookkeeper’s fault. The policy covers the defence and any settlement, but it wouldn’t cover anything done on purpose.

Professional liability vs general liability

They cover different risks, and many businesses need both.

Professional liabilityGeneral liability

How much does professional liability insurance cost?

There isn’t one price. What you pay depends on what you do, how much you earn and how much protection you want. The only reliable number is a quote for your own business, and Clearly Rate doesn’t set prices. The insurer does.

What affects the price

  • Your profession and the services you offer
  • Annual revenue
  • The limit and deductible you choose
  • Your claims history
  • The contracts you sign, which sometimes require a minimum limit
  • How long you’ve been in business

How to keep your premium down

Describe your work accurately, since gaps between what you do and what you told the insurer can cause problems at claim time. Choose a limit that matches your contracts and the size of your projects. Ask what a higher deductible would save, and whether you’re comfortable paying that amount yourself.

Is professional liability insurance required?

No general law requires it, but you’re often required to have it in practice.

SituationWhat’s usually required
You sign contracts with clientsMany contracts set a minimum limit and ask for proof of cover before work starts
You work in a regulated professionYour regulator or professional body may require it, or run its own program
You work for larger organizationsProcurement teams commonly ask for proof of professional liability insurance

What professional liability insurance doesn’t cover

Professional liability responds to financial-loss claims about your work. It isn’t a catch-all. It generally won’t cover:

  • Bodily injury or property damage, which falls under general liability
  • Intentional wrongdoing, fraud or criminal acts
  • Disputes over fees you’re owed, on their own
  • Data breaches, which usually need a separate cyber policy
  • Problems you already knew about before the policy started
  • Promises in a contract that go beyond your normal legal duty, such as guaranteeing a result

Exclusions vary by insurer, so read the list before you buy.

How a claim gets handled

01
Report it straight away
Tell your insurer as soon as you’re aware of a claim. Most policies require prompt notice, even for a claim you think is groundless.
02
The insurer takes on the defence
Your insurer assigns defence counsel and covers the legal costs.
03
Settlement or judgment
If the claim is settled or a judgment is awarded, your policy pays out up to your limit. You’re responsible for anything above it.

Claims-made cover

Most professional liability policies are written on a claims-made basis. That means the policy has to be in force when the claim is made, not only when the work was done. If you let a policy lapse, a claim about past work may not be covered. Ask about the retroactive date, which sets how far back your work is covered, and what happens if you close your business or retire.

Business insurance FAQs

Is professional liability the same as errors and omissions insurance?
Yes. They’re two names for the same coverage. “Professional liability” is more common in general business settings, while “E&O” is used more often in industries such as real estate and financial services.
How much coverage do I need?
It depends on your contracts and on how much a client could realistically lose. Many client contracts set a minimum limit, so check yours first. If there’s no contractual minimum, size your coverage to the worst realistic client loss for your kind of work. A licensed insurer can help you compare limits.
Does this cover cyberattacks or data breaches?
Not usually. Professional liability covers claims about your professional advice or service. A data breach is typically covered by a separate cyber insurance policy.
Can I get this as a sole proprietor?
Yes. Coverage isn’t limited to incorporated businesses. Freelancers and sole proprietors who give professional advice or services are exactly who this policy is built for.
Does it cover work I did before I bought the policy?
It depends on the policy’s retroactive date. Some policies cover earlier work back to a set date, while others cover only work done after the policy starts. Ask your insurer before you buy.
Do I still need it if I already have general liability?
Usually, yes. General liability covers injury and property damage, but not claims that your advice or service cost a client money. That’s what professional liability is for.
